A new three-level zero voltage switching (ZVS) pulse-width modulation (PWM) converter with the balanced output currents is presented for medium input voltage and high load current applications. Three-level converter with two clamped diodes and one flying capacitor is adopted to reduce the voltage stress of power semiconductors for medium voltage application and achieve ZVS operation for power MOSFETs...
This paper presents a new DC/DC converter for high input voltage and high load current applications. In order to adopt low voltage rating power devices in high voltage applications, two split capacitors with four active switches are used in the primary side to reduce the voltage stress of power switches at Vin/2. Two flying capacitances are used in order to automatically balance two split capacitor...
A new DC/DC converter is presented for high input voltage and high load current applications. In order to reduce the converter size and achieve high circuit efficiency, MOSFETs with high switching frequency are adopted in the converter. To achieve high circuit efficiency, two half-bridge converters are connected in series to reduce the voltage rating of power switches and asymmetric pulse-width modulation...
